We load the endpoint (and S3 credentials) from a .env file, so they're not immediately available at the time of from clearml import Task .
It's a convenience thing, rather than exporting many environment variables that are tied together.
SuccessfulKoala55 CostlyOstrich36 actually it is the import statement, just finally got around to the traceback:

Hi UnevenDolphin73 , basically the configuration loading is deferred, but once it's loaded it's not re-loaded. As long as you won't call any ClearML SDK method before setting the env vars, I think you should be fine
Setting the endpoint will not be the only thing missing though, so unfortunately that's insufficient 😞
Hey SuccessfulKoala55 ! Is the configuration file needed for Task.running_locally() ? This is tightly related with issue #395, where we need additional files for remote execution but have no way to attach them to the task other then using the StorageManager as a temporary cache.
Hmmm Regarding your issue you can use the following env vars to define your endpoint
https://clear.ml/docs/latest/docs/configs/env_vars/#server-connection
What is your usecase? Do you want to change the endpoint mid run?
So the config loading is not deferred until execution 😞
From looking at the code it should be fine, I think (i.e. won't load the configuration)
I see, okay that already clarifies some stuff, I'll dig a bit more into this then! Thanks!
You don't load the configuration during from clearml import Task config is loaded during Task.init() So you can make all your configuration additions up to the point Task.init() is run
That's what I thought too, it should only look for the CLEARML_TASK_ID environment variable?
Would it also be loaded on e.g. Task.running_locally() ?
